What dry suction does and when to use it

Dry suction on the Bissell Revolution pulls moisture out of carpet fibers without spraying cleaning solution. You use it after wet cleaning to remove water, or on its own to freshen carpet and pull up loose dirt and pet hair. The machine's motor creates a vacuum that draws liquid into the tank — the same way a regular shop vac works, but designed for carpet texture.

Dry suction is useful when you want to speed up drying time after a wet clean, when you need to refresh carpet between deep cleans, or when you have pet hair or surface dust but no stains. It will not remove set-in spots or heavy soil the way wet cleaning does, but it pulls moisture faster than letting carpet air-dry.

Key Takeaways

  • Empty the clean water tank and leave the dirty water tank in place before you start dry suction mode.
  • Press the power button, then flip the mode switch to the suction-only setting — no solution sprays in this mode.
  • Push the machine forward and backward over the carpet in overlapping passes, moving slowly to let the vacuum pull water up.
  • Empty the dirty water tank when it reaches the fill line, because a full tank stops suction performance.
  • Dry suction takes two to four passes per area to remove most moisture, depending on how wet the carpet is.

Set up the machine for dry suction mode

Start by making sure the clean water tank is empty or removed entirely. The Bissell Revolution will not spray solution when you switch to dry suction, but an empty tank prevents confusion and keeps the machine lighter. Check that the dirty water tank is seated firmly in place — this is where moisture gets pulled during suction.

Plug the machine in and fill it with water if you plan to use it for wet cleaning first. If you are starting with dry suction only, you can skip the water step. Make sure the power cord is fully extended and you have a clear path across the carpet you want to clean.

Switch to suction-only mode

Press the main power button on the handle. The machine will hum and the motor will start. Look for the mode switch — on most Bissell Revolution models, this is a lever or dial near the trigger or on the side of the handle. Flip or turn it to the setting marked for suction only, dry mode, or sometimes labeled with a water droplet icon with a line through it.

Once you switch modes, the spray trigger will not release solution even if you press it. This is normal and prevents accidental spraying. Some models have a light that changes color or turns off when you are in dry mode — check your manual to confirm your machine's indicator.

Push the machine across the carpet in overlapping passes

Start at one corner of the room or the area you want to dry. Push the machine forward slowly — faster movement means less time for the vacuum to pull moisture up. Make a pass across the width of the carpet, then pull the machine back toward you. Overlap each pass by a few inches so you do not miss strips.

The machine will be heavier when the dirty water tank fills, so empty it when you see water reach the fill line marked on the tank. A full tank reduces suction power and can cause the motor to work harder. Most carpet needs two to four passes per area; heavily wet carpet may need more. You will notice the carpet feeling drier and the sound of the motor changing slightly as less water comes up.

Empty the dirty water tank regularly

When the tank reaches the fill line, stop and unplug the machine. Locate the dirty water tank — it sits at the back or bottom of the machine depending on your model. Twist or press the release buttons on either side and pull the tank straight out.

Carry the tank to a sink or toilet and empty the water down the drain. Rinse the tank with clean water if visible debris is inside. Slide the tank back into place until you hear or feel it click or lock. Plug the machine back in and continue. Emptying the tank every 10 to 15 minutes of use keeps suction strong and prevents overflow.

Finish and store the machine

When you are done with dry suction, press the power button to turn off the motor. Unplug the machine from the wall outlet. Empty the dirty water tank one final time so it does not sit full overnight — stagnant water can develop odor and mold.

Rinse the dirty water tank with clean water and leave it to air-dry before you store it. Coil the power cord loosely and store the machine upright in a dry closet or garage. If you used wet cleaning before dry suction, make sure both tanks are empty and dry before you put the machine away.

Frequently Asked Questions

Can I use dry suction right after wet cleaning without emptying the clean water tank?

No. Empty the clean water tank first so the machine does not accidentally spray solution during suction mode. The tank should be completely removed or empty before you switch to dry mode.

How long does it take to dry carpet with dry suction?

Most carpet dries in 30 minutes to two hours after dry suction, depending on how wet it was and how many passes you make. Dry suction cuts drying time roughly in half compared to air-drying alone, but does not remove all moisture — some air circulation helps finish the job.

What if the machine loses suction power halfway through?

Check whether the dirty water tank is full. A full tank is the most common reason suction drops. Empty it and try again. If suction is still weak, the filter may be clogged — rinse it with clean water and let it dry before using the machine again.

Do I need to add water to the clean tank for dry suction?

No. Dry suction uses only the vacuum motor, not the spray system. Leave the clean water tank empty or removed. You only fill the clean tank if you plan to switch back to wet cleaning mode.
